Question

Euro Norms place limits on the amount of an emission of gas in automobiles. The gas is :

• A. ${\text{CO}}_2$
• B. ${\text{CO}}_2$
• C. Nitrogen oxides
• D. ${\text{O}}_3$

Answer 1

The correct option is C Nitrogen oxides

The Euro norms require manufacturers to reduce the existing Polluting Emission Levels in a more efficient manner by making certain technical changes in their vehicles.

The EURO I norm will be applicable to Mumbai from January 1, 2000 while the EURO II norm will be applicable to MUMBAI from 1st APRIL 2000.

In the European Union, emissions of nitrogen oxides $\text{(NOx)}$, total hydrocarbon $\text{(THC)}$, non-methane hydrocarbons $\text{(NMHC)}$, carbon monoxide $\text{(CO)}$ and particulate matter $\text{(PM)}$ are regulated for most vehicle types, including cars, trucks (lorries), locomotives, tractors and similar machinery, barges, but excluding seagoing ships and aeroplanes. For each vehicle type, different standards apply.
